ZnTe nanoparticles thin films were prepared at different substrate temperature (325, 425,525,625K) on a glass substrate by using Pulsed Laser deposition technique (PLD) under vacuum about 10-5 Torr. The Nd-Yag Q-Switch laser with wave length (1064 nm), frequency (5 Hz), and fluency (0.477 J / cm2) were employed to deposit ZnTe thin films. The as deposited of ZnTe nanoparticles thin films were investigated by X-ray diffraction (XRD), Scanning electron microscopy (SEM), Electron dispersion X-ray (EDX), Atomic force microscopy (AFM) and UV-VIS Spectrophotometer. XRD investigations confirmed the increasing in the crystallite size about (42.64, 44.02, 82.66 and 86.64nm) with increase substrate temperature in the range (325K, 425K, 525K and 625K), respectively.
